  Conventionally, as described in Patent Document 1, a container body including a bottom wall part, a front wall part fixed to the bottom wall part and a pair of left and right side wall parts, and having an opening part at the rear part, and the opening A container having a tailgate attached to a container main body so that a part can be opened and closed is known. Since the container is formed in a box shape by a bottom wall portion, a front wall portion, a pair of side wall portions, and a tailgate, dust can be accommodated in the container.

Japanese Patent No. 3638916

  However, in the container described in Patent Document 1, the opening of the container main body rear portion (the rear surface of the side wall portion and the rear surface of the bottom wall portion) is closed by a tailgate. Therefore, if minute deformation occurs during the manufacture of the container main body or the tailgate, a gap is generated between the container main body rear portion and the tailgate when the opening at the rear portion of the container main body is closed by the tailgate. Therefore, when sewage is generated from the dust contained in the container, the sewage leaks from the container through the gap between the rear of the container body and the tailgate even if the opening at the rear of the container body is closed by the tailgate. And the surrounding environment is deteriorated.

  Therefore, in order to prevent sewage from leaking through the gap between the rear part of the container body and the tailgate, a waterproof seal member is provided on the rear face of the side wall part and the rear face of the bottom wall part. May be interposed between the container body and the tailgate to fill the gap and prevent leakage of sewage.

If it is going to be attached, the seal member must be bent at the corner where the bottom wall and the side wall are fixed. However, when the seal member is bent, a substantially arc-shaped bent portion is formed. Therefore, when the seal member is bent and attached to the rear surface of the bottom wall portion and the rear surface of the side wall portion, the bent portion of the seal member becomes the rear surface of the bottom wall portion. And it protrudes toward the inside of a container main body from the rear surface of a side wall part. Then, since the bent portion of the seal member does not come into contact with the rear surface of the bottom wall portion and the rear surface of the side wall portion, a gap is generated between the seal member, the bottom wall portion and the side wall portion, and the sewage in the container is discharged outward. The problem of leaking out occurs.

  Since the problem is caused by a bent portion in the seal member, the seal member is divided into a plurality of parts to be attached to the rear surface of the bottom wall portion and the rear surface of the side wall portion without bending the seal member. It is conceivable to stick it to the part. However, when the seal member is divided, a gap is generated between the divided seal member and the seal member, and sewage in the container leaks outward from the gap.

The second seal bracket 83 is fixed to the first seal bracket 81 by welding.

Next, with reference to FIG. 9, 10, the case where dust is collected using the container C of this embodiment is demonstrated.
FIG. 9A is a side view showing the state immediately before the start of the operation of loading the container placed on the ground onto the cargo handling vehicle by the cargo handling device, and FIG. 9B is the operation of loading the container onto the cargo handling vehicle. 10 (c) is a side view showing a state in which the container is mounted on the cargo handling vehicle and the cargo handling vehicle can run, and FIG. 10 (d) is the cargo handling device. It is a side view which shows the state which inclined the container back by.

  As shown in FIG. 10 (d), the cargo handling vehicle V is provided with a cargo handling device L on the chassis frame 1 for loading and unloading the container C between the ground and the vehicle body. More specifically, a cab D is provided at the front of the chassis frame 1 of the cargo handling vehicle V. A cargo handling device L is provided on the chassis frame 1 via the subframe 2 behind the cab D.

  The loading / unloading device L loads and unloads the container C between the ground and the vehicle body by engaging a hook F provided at the front portion of the loading / unloading device L with a lift bar 32 provided on the front wall portion 30. It is possible to perform an operation or to perform a dumping operation that tilts the container C toward the rear of the vehicle.

A loading / unloading operation and a dumping operation by the cargo handling device will be briefly described below.
When the container loading operation for loading the container placed on the ground onto the cargo handling vehicle is performed, as shown in FIG. The vehicle V is moved backward, and the hook F of the cargo handling device L is engaged with the lift bar 32 of the container C. Then, after the hook F is engaged with the lift bar 32, the container C is lifted as shown in FIG. 9B by rotating the arm portion of the cargo handling device L forward of the vehicle, and then FIG. As shown in c), the container C is mounted on the cargo handling vehicle V. When the container unloading operation for unloading the container C from the cargo handling vehicle V to the ground is performed, the loading operation may be reversed. Further, when performing a dumping operation in which the container C mounted on the cargo handling vehicle V is tilted backward on the cargo handling vehicle V, the arm portion of the cargo handling device L is made substantially straight by an arm portion locking device (not shown). Then, the container C can be tilted backward on the cargo handling vehicle V as shown in FIG. 10 (d) by rotating the arm portion of the cargo handling device L. As a result, by the above-mentioned container unloading operation, the dust is put into the container C placed on the ground, and the container C filled with the dust is mounted on the cargo handling vehicle V by the container loading operation and is transported to the garbage disposal site. Can collect dust efficiently

  By the way, when the dust thrown into the container has moisture, sewage may be generated from the dust, but the container is placed on the ground or loaded on the cargo handling vehicle V by the container loading / unloading work. If the sewage inside leaks, the sewage scatters to the surroundings, deteriorating the surrounding environment. However, in the case of the container C of the present embodiment, a bracket 70 having a mounting portion 71 is fixed by welding at a corner where the side wall portion 40 and the bottom wall portion 20 are joined by welding. Accordingly, when one seal rubber 82 is bent and attached to the rear surface 24a of the bottom wall reinforcing member 24 and the rear surface 44a of the side wall reinforcing member 44, the bent portion generated by bending the seal rubber 82 is the rear surface of the mounting portion 71. Since it is disposed above, the seal rubber 82 can be fixed to the rear surface 24 a of the bottom wall reinforcing member 24, the rear surface 44 a of the side wall reinforcing member 44, and the rear surface 71 a of the mounting portion 71. Therefore, leakage of dirty water from the gap between the container main body (the rear surface 24a of the bottom wall reinforcing member 24, the rear surface 44a of the side wall reinforcing member 44, the rear surface 71a of the mounting portion 71) and the seal rubber 82 can be prevented.

  Further, the seal rubber 82 is attached to the rear surface 24a of the bottom wall reinforcing member 24, the rear surface 44a of the side wall reinforcing member 44, and the rear surface 71a of the attachment portion 71 via the first seal bracket 81, and the rear end of the seal rubber 82 is The bottom wall projecting portion 25, the side wall projecting portion 45, and the connecting portion 72 of the bracket 70 are projected rearward from the rear ends of the bracket 70, and can contact the tailgate 60. Therefore, the seal rubber 82 is interposed between the container main body and the tailgate 60, thereby filling the gap between the container main body and the tailgate 60 and preventing leakage of dirty water from the gap between the container main body and the tailgate 60. . Therefore, the clearance gap between the containers C can be made and the leakage of the sewage from the container C can be prevented.

  Here, in the container C of this embodiment, the guide part 73 is provided in the bracket 70 which has the attachment part 71, and it is comprised so that the guide part 73, the bottom wall part 20, and the side wall part 40 may become a continuous surface. Yes. For this reason, usually, a part of the opening 50 is covered by the mounting portion 71 in the opening 50 at the rear of the container main body, so that the container C is handled by the cargo handling vehicle V with the locking device 62 of the tailgate 60 released. When tilted backward, a part of the dust in the container C is caught by the mounting part 71 and is not discharged, but the guide part 73 guides the dust in the container C to the opening 50 not covered by the mounting part 71. Therefore, the entire amount of waste in the container C can be discharged without removing the dust caught on the mounting portion 71, so that the discharge operation is easy.

  Furthermore, the bracket 70 fixed to the container C of the present embodiment is configured to fix the attachment portion 71 of the bracket 70 to the side wall portion 40 and the bottom wall portion 20 by welding. Thereby, when the bracket 70 is attached to the container C, the position adjustment performed so that the rear surface 71a of the attachment portion 71, the rear surface 24a of the bottom wall reinforcing member 24, and the rear surface 44a of the side wall reinforcing member 44 are flush with each other is easy. Therefore, the bracket 70 can be easily attached.

FIG. 11 is a diagram according to the second embodiment of the present invention, and is an enlarged perspective view of a main part showing a bracket mounting state attached to a container.
The basic configuration of the second embodiment of the present invention is the same as that of the first embodiment of the present invention, but the difference between this embodiment and the first embodiment of the present invention is as follows. In the first embodiment, the mounting portion 71 is a pentagonal plate material, and the corner of the rear portion of the container C is closed by the mounting portion 71, whereas in the second embodiment, as shown in FIG.

Therefore, the seal rubber 82 is interposed between the container main body and the tailgate 60, thereby filling the gap between the container main body and the tailgate 60 and preventing leakage of dirty water from the gap between the container main body and the tailgate 60. .

In the case of the above configuration, since the hole 90 exists in the container main body, it is considered that the sewage in the container flows out of the container through the hole 90, but one side 73 a of the guide portion 73 is formed on the side wall portion 40. The other side 73b of the guide portion 73 is formed on the inner surface so as to contact the inner surface of the bottom wall portion 20, and the contact portion is fixed by welding. Therefore, since the sewage in the container is prevented from flowing into the hole 90 by the guide portion 73, the sewage in the container can be prevented from leaking out of the container also in the second embodiment.

FIG. 12 is a diagram according to a reference example and is an enlarged perspective view of a main part showing a bracket mounting state to be mounted on a container. The basic configuration of the reference example is the same as the first embodiment of the present invention, the side walls of the Reference Example, different from the first embodiment of the present invention, the bracket 70 is a container C The difference is that it is formed integrally with the portion 40. More specifically, as shown in FIG. 12, a protruding portion that protrudes toward the inside of the container is formed in the lower portion of the side wall reinforcing member 44, and the protruding portion serves as an attachment portion 71 ″.
